Abstract
The present invention provides apparatus that features a signal processor or processing module configured to receive signaling containing information about an adaptive or self-calibrating set point control curve and a varying equivalent system characteristic curve based at least partly on an instant pump pressure and a flow rate using an adaptive moving average filter, and equivalent hydronic system characteristics associated with the instant pump pressure and the flow rate to corresponding motor power and speed reconstructed and remapped using a discrete numerical approach; and determine an adaptive pressure set point, based at least partly on the signaling received.
